Detailed Description

2D random walk mobility model.

Each instance moves with a speed and direction choosen at random with the user-provided random variables until either a fixed distance has been walked or until a fixed amount of time. If we hit one of the boundaries (specified by a rectangle), of the model, we rebound on the boundary with a reflexive angle and speed. This model is often identified as a brownian motion model.
